i bought the extra quart when I did mine. I wanted it thick and it came out well. I would suggest getting and extra quart

 

So do you guys recommend taping the top of the bed off or just springing for the bed caps?

 

Bed caps will hold water under them and eventually rot out

 

Understand, How about if I put the hurculiner under the bed caps. My problem is that i don't trust myself to get the clean lines that look so good on so many trucks. I really like the Diamond Steel caps that are black.

 

Well its not to hard you can u eye ball it pretty good.

 

mine lines arent even but I'm going to tape it off again and take the herc and just go rite over that area and then call it a day.
